3.2.3 Base Unit Orientation
Install the base unit so that the rear panel faces away from the equipment storage
opening. This provides the most protection to the cable connections and any
antennas on the rear panel.
In a typical installation, the system powers on automatically when the vehicle
ignition switch is on, and shuts down automatically when the ignition switch is off.
Therefore, you do not normally use the Power Reset button on the rear panel in
such an installation. If you need to perform a manual power up or power down,
the clearances specified in
ensure adequate access to the power button.
3.2.4 Power Connection
The oMG system requires a 12V DC or 24V DC power source. In most
installations, you use one of the following sources:
•
The main battery of the vehicle; power to the oMG system is switched by the
vehicle ignition switch.
•
A separate 12V DC or 24V DC battery that powers other special equipment in
the vehicle; power to the oMG system is switched by the master switch of this
power system.
Note: In most contexts, this manual refers only to the case of connecting the system to the
vehicle battery and switching power with the ignition switch. You can interpret this instead
to mean the separate battery and its master switch.
